How to win Facebook Hacker Cup?


Point Structure
Each problem is worth a single point. The contestant with the highest score wins. Points scored in one round are used only to determine standing in that round. Points do not carry over from Online Round 1 to Online Round 2.

Penalty Time and Ties
If there is a tie in points, the contestant with the lowest penalty time wins.

Penalty Time = Submission time of the last input you correctly solve (time is measured from start of contest)
